FASHION Week can be overwhelming for a young reality-TV star, and Lo Bosworth of “The Hills” was a little flustered by all the backstage bustle. Grabbing a ham-and-cheese sandwich at the Mercedes-Benz Star Lounge yesterday after attending the Nanette Lepore show, she told Buzz, “I need to work on my ‘stay calm’ skills.” She wanted to say more, but co-star Lauren Conrad pulled her out the door to catch their car.

* Swimming through the pool of cool at the Prada party Tuesday night, Leighton Meester said she was having fun being one of the stars of the Fashion Week social scene. “As long as you keep your head on your shoulders and can distinguish between the real and the fake,” she told us. “That’s why a label like Prada is important. You can appreciate the originality that makes it real fashion.”

* Malin Akerman, the bombshell star of the upcoming “Watchmen” film, was a fan of the chocolate cake at the Prada party, but told Buzz that the pinks and pastels of Fashion Week are not necessarily her thing. “I’m a rock ‘n’ roll fan. I love leather, dark eyes, messy hair, the whole thing.”

* We know he looks good in a Speedo and gold medals, but Olympic swimmer Ryan Lochte told Buzz at Vivienne Tam‘s after-party that he soon hopes to dive into the fashion biz. “I want to be a model, that’d be awesome,” said Lochte. “Calvin Klein, Armani, stuff like that.”

* At the Cinema Society and Vanity Fair party for “Appaloosa,” there was a buffet table of comfort food including BBQ ribs, fried chicken and mac & cheese. “I’m just having the salad,” declared supermodel Carol Alt. Nigel Barker – one of the first at the table – happily gave in to the grease and nabbed a fried drumstick.

Fame goes hand-in-hand with fashion this week, and real housewife Alex McCord says any fashionistas who are hoping for their own reality show should think about acting and improv classes. “If you want your own reality show, go watch the Upright Citizens Brigade,” she advised us. But husband Simon warned that no matter how well you can present yourself on camera, when it comes to reality TV, “the devil is in the editing.”

When rumors started to spread that Anna Wintour would be visiting Apotheke for Rodarte’s after-party, one had to wonder if the icy editor’s presence would bring the room temperature down a couple degrees. Instead, the place lit up when a striking Keira Knightly popped in shortly before midnight.

Possible soon-to-be reality TV star Devorah Rose has been turning down offers from makeup artists backstage to cover the huge black and blue bruises on her knee and back, which she received when a fellow cast member on Bravo’s “Social Heights” threw her in a swimming pool during a taping. “Bruises are the new accessory this season,” Rose joked.
